Title:
TRAIN LOCATION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/117192
Kind Code:
A1
Abstract:
A train location detection device (1), provided with a radiowave arrival angle calculation unit (14), a ground-based radio device location acquisition unit (13), a train location calculation unit (15), a train location correction amount calculation unit (16b), and a train location correction unit (17). The radiowave arrival angle calculation unit (14) calculates radiowave arrival angles on the basis of received signals received by an array antenna (11) and a reception unit (12). The ground-based radio device location acquisition unit (13) acquires information regarding the installment location of a ground-based radio device (30) from the received signals. The train location calculation unit (15) calculates the train location on the basis of the movement distance of a train (40). The train location correction amount calculation unit (16b) calculates a train location correction amount using the radiowave arrival angles calculated by the radiowave arrival angle calculation unit (14), the installment location of the ground-based radio device (30) acquired by the ground-based radio device location acquisition unit (13), and the train location calculated by the train location calculation unit (15). The train location correction unit (17) corrects the train location calculated by the train location calculation unit (15) using the train location correction amount calculated by the train location correction amount calculation unit (16b).
